During all this monitoring, I wasn’t anywhere near the rider. I didn’t even need to see them with my own eyes. Instead, I was sitting inside an apartment, following their movements through a feature on a Metropolitan Transportation Authority (MTA) website, which runs the New York City subway system.
From the article, you can get a detailed usage history of MTA transactions by simply supplying the credit card number (which they state can very often be bought on the dark web). The lack of identity confirmation to pull the report is the concern.
You want to force people to show ID to use the subway?
Why is this info even public? That’s the real issue.
Not to use the subway, to access a payment card’s complete ride history.
